基于遥感图像的煤矿区土地利用/覆盖变化

Study on land use/cover change of coal mining area based on remote sensing images

选择唐山市古冶区为试验场,以3期(1987年、1992年和2001年)TM和ETM图像为主要数据源,采用ENVI和ArcView获取计算的基础数据和景观生态学的指数模型,计算了单个地类面积变化率、土地利用程度综合指数、土地利用动态度、多度和重要度指数,并依据计算结果做了详细的分析.实验表明:古冶区土地利用结构变化呈波浪式变化,与矿山开发强度和复垦程度有密切关系,利用多种指数模型可以较好地分析煤矿区土地利用/覆盖的演变规律.

Chose Guye district Tangshan city as test field, and took three phases (1987, 1992 and 2001) of TM and ETM images as main data sources, and obtained basic data by ENVI and ArcView. The analysis of LUCC was based on the index model of ecological landscape such as the change rate of individual land type area, composite indexes of land use, dynamic degree of land use, excessive degree and importance index. The case study in Guye indicated that the structure change of land use in Guye district assumes conk change, and had close relation with the process of mine development and land reclamation. Using all sorts of index models could preferably analyze evolution rules of land use/cover in coal mining area.
